Kirk Lewis, CEO and president of Bing Metals, said in a letter to Bing that his company “may be sold” to Belleville-based L & W Engineering Co. on Nov. 13. The letter also states that the sale could result in the closure of Bing Metals' stamping and assembly production plants in Detroit.

Businesses are required under the federal Worker Adjustment and Retraining Notification Act to give notification of facility closures. The Freep says a Bing Metal sale and plant closure could result in up to 350 lost jobs.
